Description

Technical Field

[0001] This utility model belongs to the field of ceramic precursor sizing, specifically relating to a foam ceramic precursor sizing machine. Background Technology

[0002] Currently, foam ceramics are the third generation of porous ceramics, following ordinary porous ceramics and honeycomb ceramics. Foam ceramics can form countless intricate and minute pores within their interior, possessing numerous advantages such as high strength, high temperature resistance, and excellent filtration and adsorption properties. They can be widely used in metallurgy, casting, chemical industry, environmental protection, light industry, food processing, and energy conservation. The organic precursor impregnation method is an important method for producing foam ceramics.

[0003] During the organic precursor impregnation process, factors such as the slurry content of the precursor impregnation, the roller spacing, and the amount of slurry dipped onto the surface of the green body directly affect the slurry holding capacity of the foam ceramic green body, and thus affect the physical properties of the finished foam ceramic product.

[0004] In the past, the preparation of foam ceramics by slurry impregnation could not be carried out by a single person, and the amount of excess slurry to be recovered was large, resulting in waste.

[0005] To address this issue, our company has developed a foam ceramic precursor slurry machine that can be operated by a single person and avoids the problem of large amounts of excess slurry being recycled. Utility Model Content

[0006] This utility model designs a foam ceramic precursor slurry machine, characterized in that: it includes a support frame, the support frame is provided with a drive device, the drive device is drivenly connected to an active pressure roller and a plurality of driven pressure rollers, the driven pressure rollers are arranged on the outer periphery of the active pressure roller, a semi-annular slurry channel is formed between the active pressure roller and the driven pressure rollers, a sponge input conveying system is provided at one end of the semi-annular slurry channel, and a green body output conveying system is provided at the other end of the semi-annular slurry channel;

[0007] The support frame is equipped with a spacing adjustment system, and the driven pressure roller is connected to the spacing adjustment system.

[0008] The support is provided with a slurry dispensing port, which is located between two driven pressure rollers near the sponge input conveying system.

[0009] Compared with existing technologies, the advantages of this invention are as follows: By setting a sponge input conveying system at one end of the semi-circular grouting channel and a green body output conveying system at the other end, the sponge input and green body output can be located on the same side of the active pressure roller. This allows for single-person operation of the foam ceramic slurrying process, avoiding the increased manual labor caused by the input and output ends not being on the same side in existing equipment. This saves labor, improves labor efficiency, and also saves equipment space. Furthermore, by setting several driven pressure rollers around the active pressure roller to form a semi-circular grouting channel, the adjacent driven pressure rollers can block the downward-flowing slurry, preventing the slurry from flowing directly to the outside. This design ensures the slurry remains in contact with the sponge within the semi-circular grouting channel, allowing for ample contact between the sponge and the slurry and significantly reducing the generation of secondary recycled residue and waste. The spacing adjustment system allows for precise adjustment of the distance between the driven and driven rollers, accommodating slurry application requirements for sponge precursors of various thicknesses. Furthermore, the slurry distribution port between the two driven rollers in the sponge input conveying system allows the slurry to enter from the top of the semi-circular grouting channel, enabling the sponge to be squeezed before being coated with slurry. This ensures the slurry is distributed onto the sponge during the grouting process within the semi-circular grouting channel, avoiding the excessive recycled residue that would result from coating the sponge before input.

A handle is provided at the other end of the lead screw.

[0022] Preferably, the lead screw is provided with a scale.

[0023] The beneficial effects of adopting the above-mentioned further technical solution are as follows: by rotating the lead screw, one end of the lead screw is held in the holding hole, and rotating the handle drives the slider to slide in the driven pressure roller channel.

[0024] Furthermore, the gear-driven lifting adjustment component includes a threaded rod, which is rotatably mounted on a bracket.

[0028] Furthermore, the sponge input conveying system is not higher than the highest point of the active pressure roller, the billet output conveying system is lower than the lowest point of the active pressure roller, and a gap is provided between the sponge input conveying system and the billet output conveying system;

[0029] The sponge input conveying system includes a conveyor belt, a conveyor roller, and a drive device. The conveyor roller is connected to a motor.

Since the sponge input conveying system is located above the green body output conveying system, it can ensure that the sponge input and the green body output are on the same side of the semi-circular slurry channel. This allows for single-person operation of the foam ceramic during the slurrying process, avoiding the situation where the input and output ends of existing equipment are not on the same side, which leads to increased manual labor, saves labor, improves labor efficiency, and saves equipment space.

This allows the sponge precursor to be coated with slurry on the reverse side, improves the one-time slurry application rate, and achieves the purpose of simultaneous front and back slurry application, simplifying the process flow.

[0039] Furthermore, the angle between the line connecting the axis of the driven roller to the axis of the driving roller is α, where α = 52°; the angle between the line connecting the axis of the driven roller near the sponge input conveying system to the axis of the driving roller and the sponge input conveying system is β, where β = 60°; and the angle between the line connecting the axis of the driven roller near the billet output conveying system to the axis of the driving roller and the billet output conveying system is γ, where γ = 92°.

At the same time, it ensures that the sponge is smoothly squeezed and sized in the semi-circular slurry channel, and the sponge can turn in the semi-circular slurry channel, so that the front slurry and the back slurry can be carried out at the same time, which simplifies the process flow.

[0050] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model.

[0051] Example 1:

[0052] like Figures 1-5As shown: This embodiment provides a foam ceramic precursor sizing machine, including a support 1. The support 1 is equipped with a drive device 2, which is connected to an active pressure roller 3 and five driven pressure rollers 4. The driven pressure rollers 4 are located on the outer periphery of the active pressure roller 3, and a semi-annular sizing channel 5 is formed between the active pressure roller 3 and the driven pressure rollers 4. A sponge input conveying system 6 is provided at one end of the semi-annular sizing channel 5, and a green body output conveying system 7 is provided at the other end of the semi-annular sizing channel 5. A spacing adjustment system 8 is provided on the support 1, and the driven pressure rollers 4 are connected to the spacing adjustment system 8. The support 1 is provided with a sizing port 9, which is located between two driven pressure rollers 4 near the sponge input conveying system 6. A sponge input conveying system 6 is installed at one end of the semi-circular grouting channel 5, and a green body output conveying system 7 is installed at the other end of the semi-circular grouting channel 5. This allows the sponge input and green body output to be located on the same side of the active pressure roller 3, enabling single-person operation during the grouting process of foam ceramics. This avoids the increased manual labor caused by the input and output ends not being on the same side in existing equipment, saving labor, improving labor efficiency, and saving equipment space. Several driven pressure rollers 4 are arranged around the active pressure roller 3 to form a semi-circular grouting channel 5. The adjacent driven pressure rollers 4 can block the downward flowing grout, preventing the grout from flowing directly to the outside and keeping the grout in a semi-circular shape. The grouting channel 5 contacts the sponge, allowing the sponge to fully contact the grout within the semi-circular grouting channel 5, significantly reducing the generation of secondary recycled residue and waste. The spacing adjustment system 8 allows for precise adjustment of the distance between the driven roller 4 and the driving roller 3, thus adapting to the grouting requirements of sponge precursors of various thicknesses. By setting a grout distribution port 9 between the two driven rollers 4 of the sponge input conveying system 6, the grout can enter from the upper side of the semi-circular grouting channel 5, allowing the sponge to be squeezed before being coated with grout. This ensures that the grout is distributed onto the sponge during the grouting process within the semi-circular grouting channel 5, avoiding the generation of a large amount of recycled residue caused by coating the sponge before input.

At the same time, the gear-driven lifting adjustment components 82 can drive the driven pressure rollers 4 to rotate as they move up and down. The positioning gear 83 is set on the drive roller drive shaft 112, which allows the power to be transmitted from the drive pressure roller 3 to the driven pressure rollers 4 around it.

By adjusting the lifting gear 824 up and down, the lifting gear 824 meshes with the driven roller gear 41. The rotation of the threaded rod 821 drives the lifting gear 824 to rotate, thereby driving the driven pressure roller 4 to rotate. The locking nut 1 823 and the locking nut 2 825 can lock the lifting gear 824 after it has rotated and risen on the threaded rod 821, preventing the lifting gear 824 from slipping.

A gap is provided between the sponge input conveying system 6 and the blank output conveying system 7. The sponge input conveying system 6 includes a conveyor belt 61, a conveyor roller 62, and a drive device 63. The conveyor roller is driven by a motor. The blank output conveying system 7 includes a conveyor belt 71, a conveyor roller 72, and a drive device 73. The conveyor roller 72 is driven by the drive device 73. The drive device 63 drives the conveyor roller 62 to rotate, thereby moving the conveyor belt 61. This allows the sponge input conveying system 6 to carry the sponge precursor into the semi-annular slurry channel 5. The drive device 73 drives the conveyor roller 72 to rotate, thereby allowing the blank output conveying system 7 to carry the foam ceramic blank out of the semi-annular slurry channel 5.

[0062] The active pressure roller 3 and the driven pressure roller 4 are arranged in parallel, as are the sponge input conveying system 6 and the green body output conveying system 7. The active pressure roller 3 and the driven pressure roller 4 rotate in opposite directions, and the sponge input conveying system 6 is located above the green body output conveying system 7. Preferably, the active pressure roller 3 rotates counterclockwise, the driven pressure roller 4 rotates clockwise, the sponge input conveying system 6 operates counterclockwise, and the green body output conveying system 7 operates clockwise. By arranging the active pressure roller 3 and the driven pressure roller 4 in parallel and rotating in opposite directions, the sponge can enter from one end of the semi-annular slurry channel 5 and exit from the other end. The location of the sponge input conveying system 6 above the green body output conveying system 7 ensures that the sponge input and the green body output are on the same side of the semi-annular slurry channel 5. This allows for single-person operation during the slurry coating process, avoiding the increased manual labor caused by the input and output ends not being on the same side in existing equipment. This saves labor, improves labor efficiency, and conserves equipment space.

[0063] The support 1 is equipped with several scrapers 15, which are located on the outside of the semi-annular grouting channel 5 and are in contact with the surfaces of the active pressure roller 3 and the driven pressure roller 4. By setting several scrapers 15, the scrapers 15 can clean the slurry adhering to the surfaces of the active pressure roller 3 and the driven pressure roller 4 outside the semi-annular grouting channel 5, ensuring the cleanliness of the active pressure roller 3 and the absence of slurry residue on the surface of the product. This prevents the slurry from flowing out of the semi-annular grouting channel 5, allowing the slurry to remain in contact with the sponge within the semi-annular grouting channel 5 for a long time, ensuring the constant roller spacing, and facilitating the collection of excess slurry.

[0064] The angle between the line connecting the axis of the driven roller 4 to the axis of the driven roller 3 is α, where α = 52°; the angle between the line connecting the axis of the driven roller 4 closest to the sponge input conveying system 6 to the axis of the driven roller 3 and the sponge input conveying system 6 is β, where β = 60°; and the angle between the line connecting the axis of the driven roller 4 closest to the blank output conveying system 7 to the axis of the driven roller 3 and the blank output conveying system 7 is γ, where γ = 92°. Preferably, the length of the sponge is 10mm-200mm, the diameter of the driven roller 3 is 500mm-560mm, and the diameter of the driven roller 4 is 350mm-450mm. By setting the angle between the axis of the driven roller 4 and the axis of the driven roller 3 to be α, the angle between the axis of the driven roller 4 near the sponge input conveying system 6 and the axis of the driven roller 3 to be β, and the angle between the axis of the driven roller 4 near the billet output conveying system 7 and the axis of the driven roller 3 to be γ, and arranging the driven roller 4 around the driven roller 3, the smooth input of the sponge and the smooth output of the billet are ensured. At the same time, it ensures that the sponge is smoothly squeezed and sized in the semi-circular slurry channel 5, and the sponge can turn in the semi-circular slurry channel 5, so that the slurrying on the front and the slurrying on the back can be carried out at the same time, which simplifies the process flow.

[0065] This embodiment provides Example 2.

[0066] The same content as in Example 1 will not be repeated here; the different aspects of this example compared to Example 1 are as follows, please refer to [link / reference]. Figures 6-7 :

[0067] The support 1 is equipped with a slurry pump 16. The other end of the active pressure roller 3 passes through the pressure roller support 14 and the support support 12. The active pressure roller 3 is equipped with a slurry storage channel 17. The outside of the slurry storage channel 17 is equipped with a flexible nylon material 18. The slurry storage channel 17 is connected to the slurry outlet of the slurry pump 16. The slurry storage channel 17 is an annular channel or a cylindrical channel. By setting the slurry pump 16 on the support 1, the slurry can enter the slurry storage channel 17 in the active pressure roller 3 from the slurry pump 16. The driven pressure roller 4 presses the sponge precursor of the semi-annular slurry channel 5, and the slurry in the slurry storage channel 17 seeps out through the flexible nylon material 18 to the outside of the active pressure roller 3 and contact the reverse side of the sponge precursor. This allows the sponge precursor to be coated with slurry on the reverse side, improving the first-pass slurry application rate and achieving the purpose of simultaneous front and back slurry application, thus simplifying the process.
